I just tried to build Emacs 23.4, and I'm sorry to say that neither
the optimized build nor the unoptimized one crash for me.  They both
build just fine and come up without crashing.

What's the problem that causes the crash?  Is `info' or
`info->root_dir' a NULL pointer or something?

If nothing else gives a clue, diff Emacs 23.4 sources against 23.3.90,
and then apply the diffs one by one until you get the crash.  This
should pinpoint the change which causes this.
